We were very proud to introduce our brand new BOS NineT NATE KERN SPECIAL #2 at the Glemseck 2018

The American racer Nate Kern has ridden eight different BMW bikes during his career and he has won races with all of them. Nate really wants to show that the BMW R nine T can be more than a lifestyle bike. And that is exactly what he proved on the racetrack at the Glemseck riding our BOS NineT!

But not only professionals can benefit from this awesome BOS NineT Nate Kern Special performance system. You can also add some power and style to your own BMW R Nine T. Contact your dealer and order our new BOS exhaust kit!

And off course BOS Exhausts was also present! Hereby we thank you for visiting our exhibition stand last october this year. We have shown you a lot of brand new exhausts systems and some special customized bikes. If you still have any questions about our exhausts, please do not hesitate to contact us. Drive safe!

The facts behind the Euro 4 standard for motorcycles

All new models of 125 cc and up must comply with the Euro 4 regulations as of the 1st of January 2016. For existing Euro 3 models manufacturers have two options: either they adjust the model in question before the 1st of January 2017 to create a Euro 4 model or they catalogue the individual model as a predictive model and they have until the 31st of December 2018 to sell their stock -under certain conditions-.

This means that the dynamic noise must be reduced by Euro 4 with a few dB (A). Your Euro 3 muffler was allowed to make up to 80 dB (A), this is now reduced to 77 dB (A).

The well-known (removable) Db-eaters are not allowed anymore. A Db-eater must be permanently attached now, so that you have to seriously damage your exhaust to remove the Db-eater. The widely used excuse to the police: “Sorry, my Db-eater was really installed and must have fallen during the ride!” is no longer possible!

And then, the electronically controlled valves. This may be used, provided that they always work properly and are not installed with a ‘test cycle’ recognition. Electronics can recognize a ‘test cycle’ and then switch to a special program in which the valve closes and thus is suddenly much quieter. In the media, this software has become known as the ‘tamper software’.

For us as an exhaust manufacturer any new standard means a new set of challenges. Besides all modifications to produce a beautiful and better sounding exhaust, inspections have become more complicated and a costly procedure. Each new exhaust undergoes a rigorous and extensive sound test on special asphalt, before any (type) approval is given.

And perhaps you did not know it yet. As of 2020 the even stricter Euro 5 standard for all motor vehicles will be introduced.
